I've experienced something with strong parallels to what Rach is describing. Some of you may remember back to when I sought help on this forum. I'm sorry to hear you aren't back to 100% Rach. I feel I'm not either but I also feel like I can function again. Our minds are strong enough to pull it together and do what needs to be done. I have depression now and all the lingering DP/DR, fuzzy thoughts and vision, occasional sound distortion, poor appetite and sleep patterns and lack of motivation. I do feel like the supplements I'm taking are helping though. It's as if my brain is beginning to function again and work out strategies to accomodate the obvious damage.
Toria, you're not helping here. In fact you're making things far far worse.
Lastly, Rach. HPPD (I thought I had it to) in the strict sense of the disorder is hallucinogen persisting 'perception' disorder. The American Psychiatric Association prefers to narrow the term'perception' to mainly the visual sense. I tried to follow the diagnosis criteria and evaluate myself but I came nowhere near. It's mainly used for those who have recurring images such as fractals in their vision after intense (although not always) LSD use. We fit into a class of our own. Somewhere between brain damage and post drug-use mental trauma. There is a fairly dense HPPD support community on the web and a very nice forum dedicated for those afflicted with the disorder. Check it out, recount your story and see what people say. It'd be nice to slap on a name for what we have and take away the loneliness that comes with being the only person with these symptoms but I just don't see it happening for me. Hope it does for you. So far you have the closest description I've found for what's happened to me, so from that perspective, even if we're the only two people in the world with this, we're not alone
